There are 15 pearls all different, the number 01 is the biggest, which should be printed only once, all the other ones should be printed twice. You MUST use brim to print this.If you have enough time it's better to print it one at a time to prevent small defects on the surface when the head jumps from one to the others. Then you have to polish. I made a video that explain how to polish (from min 15) https://vimeo.com/111090888
